带自诊断功能的门式起重机纠偏装置

Gantry Crane Rectifying Device with Self Diagnosis Function

起重机在工作过程中,可能会因为各种原因出现跑偏现象,尤其是大跨度(大于或者等于40m)的门式起重机和装卸桥,一旦出现跑偏而不能及时发现纠正,其后果将是难以估量的。为防止工作过程中出现偏斜和啃轨事故,应设置偏斜显示或者限制装置。为了保证偏斜限制装置有效可靠的工作,分析了可能导致起重机跑偏的原因,并设计了纠偏装置的自诊断功能,实现了纠偏装置的有效可靠工作。

In the working process, crane possibly appears deviation phenomenon because ot various reasons, especially the gantry crane and loading bridges with large span （greater than or equal to 40m）, once deviation appears and cannot be discovered and corrected timely, the consequences will be immeasurable. To prevent deflection and gnawing rail accident occurred during work, the skew display or limit device should be set. In order to ensure deflection limiting device work effectively and reliably, the writer analyzes the possible cause of the deviation of the came, and designed self-diagnostic function, and it made corrective devices work effectively and reliably.
